Preliminary Propulsion and Power System Design of a Tandem-Wing Long-Range eVTOL Aircraft

Novel eVTOL aircraft configurations are picking up momentum in the emerging market of urban air mobility (UAM). These feature electrical power systems and distributed propulsion architectures, both uncommon current aircraft. As such, design lies outside bounds established frameworks poses many challenges field preliminary design. This paper presents a methodology for open rotor with batteries as source. First, propeller external dimensions calculated, then an optimised blade geometry cruise condition is computed. Thereupon, electric motors sized. The framework applied to range 400 km capacity five occupants (four passengers one pilot), focusing on central-European aimed be released 2030. final configuration battery-powered tandem-wing 12 variable-pitch, variable-speed rotors placed leading edges wings. rotate outboard-down six blades. source comprises 24 solid-state lithium nominal voltage 500 V assumed energy density Wh/kg. proposed offers possibility computing necessary numerical simulations early stages design, easily obtaining accurate estimates mass system which can improve overall analysed configuration.
